Spraying
Correct Answer:
C. Guniting
Explanation:
Guniting is the process of using a pressure hose to spray a mixture of cement and sand at high velocity onto surfaces. This technique, also known as dry-mix shotcrete, relies on compressed air to propel the material, ensuring dense compaction and strong adhesion to the structural face. It is commonly used for repairing concrete, lining tunnels, or reinforcing slopes.
